Next I'll do block/Kconfig. Eventually I expect to get to net/Kconfig which is where NET_NS is configured, but I don't know where UTS_NS and IPC_NS come from in 2.6.24.2. I expect I'll have to start patching against a git tree soon, to be sure to see the latest code. I assume this should be Linus' tree? Is there any actual documentation on user namespaces and friends? I think I grasp the pid namespaces concept; I am having a little difficulty visualising what function user namespaces performs. "provide different user info" isn't a very useful description and I'd fix it if I understood what it is supposed to mean. To make a guess at it, how about: Enable support for user namespaces. This is a function used by container-based virtualisation systems (e.g. vservers). User namespaces ensures that processes with the same uid which are in different containers are isolated from each other. Answer Y if you require container-based virtualisation like vservers. If unsure, say N. Nick. -- PGP Key ID = 0x418487E7 http://www.nick-andrew.net/ PGP Key fingerprint = B3ED 6894 8E49 1770 C24A 67E3 6266 6EB9 4184 87E7
